1. A base station, comprising:

  • a plurality of light emitting diode (LED) lights, configured to send downlink signals of an orthogonal frequency division multiple access (OFDMA) standard to a user terminal; and

    a baseband signal processing unit, configured to designate the plurality of LED lights as radio remote units of a long term evolution (LTE) mode, and to perform, by using baseband signal processing and resource management modes from an LTE system, processing and resource management on the downlink signals sent by the plurality of LED lights;

    wherein the plurality of LED lights are grouped into multiple LED light groups based on positions of the plurality of LED lights, and the baseband signal processing unit is further configured to associate each of the LED light groups with an independent carrier of the LTE mode;

    wherein the base station further comprises a radio frequency (RF) transmitter and an RF receiver, wherein;

    the RF transmitter is configured to send a downlink signal of the OFDMA standard to the user terminal by using an independent RF carrier;

    the RF receiver is configured to receive an uplink signal of a single carrier frequency division multiple access (SC-FDMA) standard sent on the independent RF carrier by the user terminal; and

    the baseband signal processing unit is further configured to perform, by using the baseband signal processing and resource management modes from the LTE system, carrier aggregation processing and resource management on downlink signals sent by the LED light groups and the RF transmitter and the uplink signal received by the RF receiver.
